Genus, Diaspis, Costa. 



(Trans., vol. xi., p. 192.) 

 1. Diaspis santali, sp. nov. 

 Puparium of female yellowish-grey in colour, sometimes with a greenish 

 tinge, outline oval ; very convex : pellicles black, very inconspicuous, placed 

 at one end of the puparium. 



Adult female orange-red in colour, reaching J- inch in length, peg-top 

 shaped ; the abdominal segment very small as compared with the rest of 

 the body, and the two next segments slightly overlap it. Abdomen ending 



in two conspicuous, prominent, median 

 lobes, and at each side of them two semi- 

 circular depressions: several branched 

 and serrated hairs in the region of these 

 lobes. There are no groups of spin- 

 nerets, nor can I detect any single ones. 

 There is no wide depression of the edge between the median lobes. 



Male puparium elongated, with black pellicle : but I have not seen the 

 insect itself. 



On twigs of Maire (Santalum cunninghamii), sent me by 0. Winkel- 

 mann, Esq., from Napier. It is in company with Rhizococcus fossor, de- 

 scribed below : but the latter is always on the leaves of the plant. 



The forms of the male and female puparia show this insect to be a 

 Diaspis, though it seems in many respects to resemble rather Aspidiotus. 

 I find no described species of the genus possessing the same features in the 

 abdominal segment, especially the absence of spinneret groups. Nor do I 

 think it is a Chionaspis. 



Genus, Fiorinia, Targioni-Tozzetti. 

 Mr. Comstock (loc. cit., p. 110), discards the above name and calls the 

 genus "Uhleria ," for the reason, he says, that Targioni, establishing it to 

 include the original species Diaspis fiorinia, changed the specific name to 

 pelludda. " According to the rules of nomenclature now generally adopted 

 by zoologists," he says " the original specific name must be restored and 

 a new generic name given." I think this is a great pity if correct, and 

 tends to introduce endless confusion, and prefer to leave the original name 

 as above. 



The characteristic feature of this genus is the great size of the female 

 pellicle of the second stage, which almost, or quite, fills the puparium. 

 1. Fiorinia minima, sp.nov. 

 Figs. 2, 3. 

 The puparium is oval, being indeed almost altogether made up of the 

 second pellicle, with a narrow edge of fibrous secretion, as shown in the
